  • Patent number: 4630938
    Abstract: A method and apparatus for determination the thermal conduction coefficient and the heat capacity of materials. The method comprises the measurements of heat flux across the sample and the momentary temperature difference between both surfaces of the sample perpendicular to the direction of heat flux during continuous change of the temperature of one of sample surfaces. The values of thermal conduction coefficient, heat capacity and thermal diffusivity are determined on the basis of an equation which defines their dependence on measured heat flux across the sample, temperature difference between the sample surfaces and the rate of the change of the temperature of one sample surface. The apparatus for measuring thermal conductivity and heat capacity contains a heater equipped with a temperature sensor of a thickness less than 1 mm, placed between two samples, one of them being the sample of material tested of a thickness less than 10 mm.
